The groundnut improvement network for Africa (GINA) germplasm collection: a unique genetic resource for breeding and gene discovery.

Cultivated peanut or groundnut (Arachis hypogaea L.) is a grain legume grown in many developing countries by smallholder farmers for food, feed, and/or income. The speciation of the cultivated species, that involved polyploidization followed by domestication, greatly reduced its variability at the DNA level.

Host Specificity Controlled by and Effector Genes in the Finger Millet Blast Pathogen in Eastern Africa.

, a devastating pathogen of finger millet (), secretes effector molecules during infection to manipulate host immunity. This study determined the presence of avirulence effector genes and in 221 blast isolates from eastern Africa. Most Ethiopian isolates carried both and .

Genome-wide association studies reveal novel loci for resistance to groundnut rosette disease in the African core groundnut collection.

We identified markers associated with GRD resistance after screening an Africa-wide core collection across three seasons in Uganda Groundnut is cultivated in several African countries where it is a major source of food, feed and income. One of the major constraints to groundnut production in Africa is groundnut rosette disease (GRD), which is caused by a complex of three agents: groundnut rosette assistor luteovirus, groundnut rosette umbravirus and its satellite RNA. Despite several years of breeding for GRD resistance, the genetics of the disease is not fully understood.
